How do I use the security keyguard on my Nokia phone (Series 40)?

Security keyguard lets you lock your phone’s keypad with a security code. The security code is asked when you unlock the keypad.

To activate or deactivate the security keyguard:

  1. Select Menu > Settings > Phone (or Phone settings or Device) > Security keyguard.
  2. To activate or deactivate, enter the current security code (The preset code is 12345).

Note: Note: Once you change your security code, the default setting is no longer valid. If you have changed your security code and do not remember the new code, contact your dealer or local Nokia Care Point. You can answer a call or make an emergency call while the security keyguard is activated.
